Styling AppCompat SearchView with AppCompat 22.1.0 is not working

Question

I defined a layout for the suggestion row, but after updating the AppCompat library to 22.1 the layout defined in the styles.xml is ignored.

This is my styles.xml file (simplified):

<style name="Theme.Upp" parent="@style/MyApp">
    <item name="searchViewStyle">@style/SearchViewStyleMyApp</item>
</style>

<style name="SearchViewStyleMyApp" parent="Widget.AppCompat.SearchView">
    <!-- Background for the search query section (e.g. EditText) -->
    <!-- <item name="queryBackground">@android:color/black</item> -->
    <!-- Background for the actions section (e.g. voice, submit) -->
    <!-- <item name="submitBackground">...</item> -->
    <!-- Close button icon -->
    <!-- <item name="closeIcon">...</item> -->
    <!-- Search button icon -->
    <!-- <item name="searchIcon">...</item> -->
    <!-- Go/commit button icon -->
    <!-- <item name="goIcon">...</item> -->
    <!-- Voice search button icon -->
    <!-- <item name="voiceIcon">...</item> -->
    <!-- Commit icon shown in the query suggestion row -->
    <!-- <item name="commitIcon">...</item> -->
    <!-- Layout for query suggestion rows -->
    <item name="suggestionRowLayout">@layout/layout_suggestion_entry</item>
</style>

Even if I try to change the queryBackground it is not working.

Any ideas why?

After looking into the newest library source it loooks like it was intended to make SearchView match material design guidelines, so as a result default style is without underline and hint icon.

To apply your own style first you have to define your SearchView style in styles.xml like this:

<style name="SearchViewStyleMyApp" parent="Widget.AppCompat.SearchView">
    <!-- Background for the search query section (e.g. EditText) -->
    <!-- <item name="queryBackground">@android:color/black</item> -->
    ...
    <!-- note that this is how you stye your hint icon -->
    <item name="searchHintIcon">@drawable/ab_icon_search</item>
</style>

Then you define your ActionBar/Toolbar theme overlay:

<style name="MyThemeOverlay.ActionBar" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
        <item name="searchViewStyle">@style/SearchViewStyleMyApp</item>
</style>

Next step is to add ToolBar to your layout file like this:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        android:minHeight="?attr/actionBarSize"
        app:theme="@style/MyThemeOverlay.ActionBar"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        android:elevation="4dp" />

    <FrameLayout
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</LinearLayout>

Last step is to set your Toolbar to act like an ActionBar:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

    }
}

Also note that your theme has to extend Theme.AppCompat.NoActionBar
